Answer / Monu
Callbacks are functions passed as arguments to other functions to be executed after the main function has completed. They allow for asynchronous execution, meaning the main function can continue running while the callback function is being executed elsewhere. Node.js heavily relies on callbacks for handling I/O operations.
